A runner expends an average of 4 kcal per minute during a two hour run. She want to eat a meal of
50% energy from carbohydrate, 25% of energy from protein and 25% of energy from fat, how
much protein would their meal have to contain, in order to replenish their expended energy?
Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.
The runner in question wishes to complete a two-hour run while expending 4kcal or calories per minute, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.
Since every gram of protein adds 4 calories of energy to the meal, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.

Rearrange the sentences into their most logical sequence to describe the process of energy extraction from glucose
Pyruvic acid passes from the cytoplasm into the mitochondrion.
A series of reactions break and rearrange carbon bonds to release energy and carbon dioxide.
Three molecules of ATP are produced with every pair of high-energy electrons that pass through the electron transport chain.
In total, about 36 ATP molecules are released from one molecule of glucose.
A small amount of energy is released when the bonds in a 6-carbon glucose are broken and rearranged into 3-carbon pyruvic acid molecules.
Answer:
A series if reaction break and rrarrange csrbon bonds to release energy ang carbon dioxide.
The correct sequence of energy extraction from glucose is 5, 1, 2, 3, 4 to complete the oxidation of glucose.
What is glycolysis?Thus, the phases of cellular respiration should be performed in the following order: Krebs cycle, oxidative decarboxylation, electron transport chain, and oxidative phosphorylation are the steps in glycolysis.
The process of energy extraction from glucose:
When the bonds in 6-carbon glucose are broken and reorganized into 3-carbon pyruvic acid molecules, a little amount of energy is produced. Pyruvic acid enters the mitochondrion from the cytoplasm.
Carbon bonds are broken and rearranged in a sequence of events that release energy and carbon dioxide.
Every pair of high-energy electrons travels through the electron transport chain resulting in the production of three molecules of ATP. One glucose molecule releases roughly 36 ATP molecules in total.
Therefore, the process of energy extraction from glucose start from pyruvate forming and end with the ATP formation.

Applying the systems thinking techniques, outline the practical steps that can be taken to address drought
Some practical steps to address drought may include the implementation of efficient water usage techniques, the protection of vegetation, and the use of methods to retain moisture in the soil.
What is a drought?A drought is classified as the shortage or absence of water for a prolonged period of time in a region. These can be caused by a prolonged lack of rainfall.Other factors include poor water management and lack of vegetation.Methods to avoid droughts.The planting and protection of vegetation, primarily those adapted to dry environments, is important in preventing drought.Furthermore, the correct implementation of efficient water usage techniques can aid in preventing drought by limiting the amount of water that is wasted. Lastly, the use of mulch and other water retainers can be an effective method in keeping the soil moist and aids in the previous two methods.Therefore, we can confirm that the most effective ways to avoid droughts are to practice efficient water use so as to not waste water, to plant and protect vegetation, and to use mulch and other moisture-retaining methods to keep the soil from drying.

How does meiosis most benefit a species?
It decreases the number of chromosomes.
It increases genetic variation.
It increases the number of chromosomes.
It increases mutations.
Answer:
It increases genetic variation.
Explanation:
Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.
While it could increase mutations, this might not necesarily be a good thing.
However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.

John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being dominant
Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
Using A to represent the allelesSince his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa). So for John to have an unattached earlobe, his father has to be either AA or Aa. Therefore John's genotype would be AaLearn more about genotype: https://brainly.com/question/22117
